FIELD: technological processes. ^ SUBSTANCE: invention is related to equipment of aerosol-concentrating devices, and also to devices for vacuum cracking of natural gases and oil, to gas-dispersing and gas-transporting devices, to dispersers of gas-liquid mixtures and gas dynamic systems of different components in chemical technologies, and to devices, where it is required to disperse gas and is possible to use wind energy, etc. Technical task is solved due to the fact that nozzle comprises either rigidly fixed sprayers or sprayers having devices for variation of geometric parametres, or both simultaneously, which are tightly connected to each other. Critical section of every sprayer is not less than critical section of flow-determining sprayer. Downstream flow-determining sprayer, at least one flow determining sprayer is installed, which communicates to source of overpressure. Besides, in the first sprayer on the way of gas flow, start-up sprayer is installed as untight and offset, communicating to compressor. Or at least once start-up mouthpiece is installed, but of lower size compared to every further mouthpiece. Start-up mouthpiece is communicated either to compressor or to environment. At least one mouthpiece is either installed or not installed on bracket, having axis of rotation. Sprayer, which is first on the way of gas flow, is installed closer than the rest sprayers to axis of rotation. Mouthpiece operation is guaranteed at significant variations in pressure differences, which might occur due to different brands of oil products and other technological variations, and expands field of application both for air cleaning and in equipment for particles crushing by their hitting against hard surface or for spraying of particles on surface coated with glue. Invention also expands technological resources to eliminate oil congestion and clogging of gas lines with sticky slurries. ^ EFFECT: higher reliability and efficiency. ^ 2 cl, 9 dwg |
